Technology of Sodium Gluconate

At present, the main production methods of Sodium Gluconate include Biological fermentation, Homogeneous chemical oxidation, Electrolytic oxidation, and Multi-phase catalytic oxidation, all of them have been widely studied in China.

In industrial production, Biological fermentation and Multi-phase catalytic oxidation are more widely used. In which Multi-phase catalytic oxidation method has simple process, mild reaction conditions (all kinds of the gas-liquid-solid three-phase hybrid reactor under atmospheric pressure can be used, reaction temperature control under 60 ℃), generally shorter reaction time, high conversion rate, less “three wastes” and easy processing, the characteristics of this method is the key performance of the catalyst and the circulation use of the number of times. The polyphase catalytic oxidation method has great advantages and application potential through multiple applications of catalysts, overcome the disadvantages of expensive metals and deactivation of catalysts.

A certain amount of glucose solution was prepared and added into the flask(F4), an appropriate amount of catalyst was added into the flask and the temperature was kept constant. Air is added to the solution, and a certain concentration of NaOH is added continuously to maintain a certain pH. The solution was cooled, filtered (the catalyst was recovered), the filtrate was condensed and crystallized by vacuum distillation, and the sodium gluconate crystal was obtained after air drying.

Development Of Sodium Gluconate In China

Sodium gluconate is a polyhydroxy organic acid salt widely recognized by the industry and users. It is a deep processed product of glucose, and it is also the basic raw material for the preparation of industrial standard gluconolactone, gluconate (zinc, copper, ferrous salt). In food and other industries, it can be used as a nutritional supplement, curing agent, buffering agent and so on.

It is non-toxic, has good thermal stability, no deliquescent, and has a wide range of raw materials. Because of the excellent chelating properties of sodium gluconate, it has a wide range of uses in various industries such as the chemical industry, food, medicine, light industry and so on.

Sodium gluconate is mainly used as a cement admixture in building construction. With the development of high-rise buildings and urban mixing stations in each city, it has been used as a water reducing admixture and concrete retarder for construction projects. And it has achieved considerable good results that are widely recognized by people.

China has adopted the microbial fermentation process to produce sodium gluconate. Today, many indicators such as fermentation level and extraction process have reached the world advanced level. And in some respects, it has surpassed the international level. From the perspective of demand, as an emerging industry, sodium gluconate has a large amount of concrete market. In the next few years, its application field will continue to expand and the demand in the international and domestic markets will increase, its demand will be strong.
